Hooked it up, searched in youtube for relevant video to determine settings to send vid and audio to tv. Did not plug into my home theatre receiver yet only because it was just a quick hookup. Initially, without tweaking any settings on the mac all I got was the wallpaper of the mac. After viewing the youtube video, this is how I did the settings:1) go to Systems Preferences, click on Display (the menu will be seen on the tv)2) click on Arrangement and click on Mirror Display3) go back to the menu and click Sound and select hdmi cable and that will get the sound through hdmi to your tv.and that’s all there is to it. The link I used was[…]And under $9 for the cable. Not bad.Update 5/9/2012 – connected to a/v receiver and watched a netflix streamed movie. Worked perfectly. A note of caution, if you purchase an extension to use with this cable you may not get the result you want. I got “unsupported signal….” with a skinny 10 ft cable. Other reviewers said the same thing for that cable. You might be better off opting for a longer mini display port to hdmi instead.

It really works well. I did end up having to use an aux cord for sound, my macbook pro was purchased in early 2010. Apparently middle 2010 they updated the hdmi output thing to include sound. So just know that if you purchased your macbook pro early in 2010 or before you will need an aux cord too.

I’m very satisfied with the picture of the screen on my tv, I didn’t expect it to look so clear!!
